Function

Enter a timestamp in a specific format to automatically get the time after how many hours forward or backward

Additional function

Timestamp conversion function

Def date_time_str_to_long (input_date_time_string):''the standard time format is converted to a 10-bit timestamp, such as:' 2020-01-16 08param input_date_time_string 05param input_date_time_string 09' to '1579133109': param input_date_time_string: string type, the standard time entered, such as:' 2020-01-1608Swiss 05purl 09': return: 10-bit timestamp For example, the time of '1579133109' # character type # input_date_time_string =' 2013-03-06 08VOV 05timeArray 09' # input_date_time_string = '2013-03-06 08RV 05RV 09' # convert to the time array timeArray = time.strptime (input_date_time_string) "% Y-%m-%d% H:%M:%S") # converted to timestamp timeStamp = int (time.mktime (timeArray)) print ('standard time = {}) 10-bit timestamp = {} '.format (input_date_time_string, timeStamp) # 1381419600 return timeStamp def date_time_long_to_str (timeStamp='1579133109', utc_time=0):' 'convert the 10-bit timestamp to standard time, such as:' 1579133109' to '202001-1608return timeStamp def date_time_long_to_str 05return timeStamp def date_time_long_to_str 09': param timeStamp: string type, the entered 10-bit timestamp For example: '1579133109': param utc_time: choose whether to output UTC time, set to 1, then output UTC time, UTC time = current time-8 hours Default is 0, and output is non-UTC time: return: standard time For example, '2020-01-16 008 timeStamp 05timeStamp 09' # # use datetime # dateArray = datetime.datetime.fromtimestamp (timeStamp) # otherStyleTime = dateArray.strftime ("% Y-%m-%d% H:%M:%S") # print (otherStyleTime) # 2013-10-10 23:40:00 if utc_time = 0: # use time timeStamp = int (timeStamp) TimeArray = time.localtime (timeStamp) otherStyleTime = time.strftime ("% Y-%m-%d% H:%M:%S" TimeArray) print ('input_time= {}, output_StyleTime= {}' .format (timeStamp, otherStyleTime)) # 2013-10-10 23:40:00 return otherStyleTime else: # use datetime Specify utc time 8 hours less than the current time import datetime dateArray = datetime.datetime.utcfromtimestamp (timeStamp) otherStyleTime_utc = dateArray.strftime ("% Y-%m-%d% H:%M:%S") print ('input_time= {}, output_StyleTime_utc= {}' .format (timeStamp) OtherStyleTime_utc) # 2013-10-10 15:40:00 return otherStyleTime_utc examples are as follows: 1. Obtain the time format "2030-12-02T20:00:00+08:00" 3 hours after "2030-12-02T17:00:00+08:00"

Code implementation

Def get_now_ISO_time_count (first_time_string,count_int=3600): # "2030-12-02T17:00:00+08:00" if first_time_string ='': print ('initial time cannot be empty, please confirm.') Return-1 first_time_string=str (first_time_string). Replace ('tourmaline'). Replace ('+ 08 first_time_string') '') print ('first_time_string= {}' .format (first_time_string)) count_time=int (date_time_str_to_long (first_time_string)) + int (count_int) count_str=str (date_time_long_to_str (count_time)) result=count_str [0:10] + 'qualified countss [11:] +' + 08first_time_string 00' print ("get_now_ISO_time_count_08= { } ".format (result)) return str (result)

Code call

If _ name__ = ='_ main__': print (get_now_ISO_time_count ("2030-12-02T17:00:00+08:00", 10800))

Execution result

First_time_string=2030-12-02 17:00:00

Standard time = 2030-12-02 170000000000Band 10-bit timestamp = 1922432400

Input_time=1922443200,output_StyleTime=2030-12-02 20:00:00

Get_now_ISO_time_count_08=2030-12-02T20:00:00+08:00

2030-12-02T20:00:00+08:00

Second, calculate the difference between two times, accurate to seconds def date_time_count (startTime, endTime):''calculate the difference between two times Accurate to seconds: param startTime:: param endTime:: return:''spent_times = int (date_time_str_to_long (endTime))-int (date_time_str_to_long (startTime)) print (' endTime= {}, startTime= {}, time difference = {} '.format (endTime, startTime, spent_times)) return spent_times

Code call

If _ _ name__ = ='_ main__': print (date_time_count ("2021-12-06 19:40:00", "2021-12-09 14:26:40"))

Execution result

Standard time = 2021-12-09 14-26-14-12-09 14-26-14-14-14-14-14-14-14-14-14-14-14-14-14-14-14-14-14-14-14-14-14-14-14-14-14-14-14-14-14-14-14-14-14-14-14-14-14-14-14-14-14-14-14-14-14-14-14-14-14-14-14-14-14-14-14-14-14-14-14-14-14-14-14-14-14-14-14-14-14-14-14-14-14-14-14-14-14-14-14-14-14-14-14-14-14-14-14-14-14-14

Standard time = 2021-12-06 1919 40 000010-bit timestamp = 1638790800

EndTime=2021-12-09 14-14-26-14-40-12-06 19:40:00, time difference = 240400

240400

Third, calculate the difference between two times, which can be accurate to milliseconds

Code implementation

Def date_time_count_ms (startTime, endTime):''calculate the difference between two times Can be accurate to milliseconds: param startTime:: param endTime:: return:''# enter the time format # a = parse ('2019-10-30 23 return 4315 10.123') # b = parse ("2019-10-28 lash 09 return 0813. 56212") a = parse (str (endTime)) b = parse (str (startTime)) d_count = (a-b). Days # gets the time difference of days s_count = (a-b) .seconds # gets the number of seconds in the time difference That is, from 23:43:10 to 09:08:13, excluding the preceding days and the decimal total_seconds after seconds microseconds = (a-b). Total_seconds () # all seconds difference, including days, hours, microseconds, etc. Microseconds = (a-b). Microseconds # the difference after the decimal point print ('endTime= {}, startTime= {}, time difference = {}' .format (endTime, startTime, total_seconds)) return total_seconds

Code call

If _ _ name__ = ='_ _ main__': print (date_time_count_ms ("2021-12-06 19 main__': print 40 main__': print 44.123", "2021-12-08 14 main__': print 26 Switzerland 40.567"))

Execution result

EndTime=2021-12-08 14-14-26-26-24-12-06 19-40-40-44.123, time difference = 153956.444

153956.444
